This invention relates to devices for rethrough the head of'each :section of the moving lids'or caps from jars and particuwrench is an aperture 15 and. extending larly to a "wrench for this purpose which transversely through these alinedapertl lres will clamp upon the jar cap or lid and where? is a bolt 16 having a head at one end and a byjar caps or lids which are difiicult to re-- n'ut andwasher at the other.

My wrench fits snugly all the way around the jar lid or cap and engages the top of the lid which is the rigid portion of the lid, thereby not injuring the lid in any way and eliminating any danger of crushing the threaded part ofthe glass jar.

This applies not only to the ordinary fruit jar lids of standard size but to lids for peanut butter and pickle ars.

is. equally adaptable to putting the ar caps inplace or tightening the caps.

One of the advantages of my invention is that it is applicable not only to the ordinary Mason ar caps but also to the new style glass top fruit j ar lid wherein the metal of the lid iscut away to expose atransparent glass disk within the top of the lid. With either of these styles of lid, the wrench engages the upper portion of the lid above they screw threads thereof and cannot be brought down over the screwthreads as shown clearly in Figures 3 and 4 so that when pressure is applied to thehandles of the wvrench, the wrench will not crush the screw-threads or the cap'itself or jam the cap on the jar or possibly break the mouth of the jar.

I claim: ,7 r

1.v cap wrench formed of two mating sections, each section having a head andaghandle, the head of each section having a semi-circular recessformed therein, and mating with the semi-circular recess in the other head, the outer portions of the sections outward ofvthe recesses having confrontingfaces, the outer portions of. each section outward of the recesses being transversely bored from one side edge of the head to the other side edge thereof, and a bolt passing through said bore, the bolt holding the said confronting faces in close. approximation to each other, and yield ingly holding'the handles in divergent relation whereby as thehandles are closed, the bolt-will be bent.

2. A jar cap wrench formed of two mating wooden sections, each of these sections havinga head'and a handle, the head of each section having a semicircular recess therein mating with the semi-circular recess in the other head, the heads of the two sections beyond the recesses being formed with alining bores, and a bolt passing through said bores and holding the confronting faces of the sections beyond the recesses in close approximation to each other, the handles of the sections being held in normally divergent relation by said bolt whereby as the handles are forced toward each other, the bolt will be bent, the resilience of the bolt acting to spread the sections apart when pressure on the handles is relieved.
